ever-victorious army; invincible army
A literary or historical term for an army that has never been defeated. Rare in modern everyday speech; more often encountered in historical texts, fiction, or metaphorical use.
According to legend, that general led an ever-victorious army.
Compound of 全勝 (zenshō, 'complete victory') and 軍 (gun, 'army'). The exact historical origin is uncertain; it likely arose in classical or military writings to describe an undefeated force.
